For the last several days, Windows Update has been failing to update my Office 2003 products.

I do already have the "Validation Tool" that Windows Update installs, and all of my software has legal, valid installations.

The following Updates all are Failing to install:
- Update for Microsoft Office Outlook 2003 Junk Email Filter (KB975958)
- Office 2003 Service Pack 3 (SP3)
- Update for Office 2003 (KB907417)

These all fail to install with an Error Code of 0x80070643.

Thank You, Microsoft, for this helpful, plain-English-language explanation of what went wrong! ;-)

Well, looking up "Error Code 0x80070643" using Google yielded this result:
You receive error code 0x80070643 or error code 0x643 when you use the Windows Update or Microsoft Update Web sites to install updates

This looked promising, but the way that they described to add entries to the Registry didn't work on my system, I had to use 'regedit' to do it manually.

Near the bottom of the Microsoft web page, it also had a link to this:
How to Enable Windows Installer Logging in Windows XP

What this new page described also did not work in my system, as far as finding the results of the Windows Installer logging that is turned on by the new Registry entries.

Fortunately, I already know how to find the System Logs in Windows XP, by using:
Start --> Administrative Tools --> Computer Management

So, I was able to (manually) create the log files (actually, Comma-Separated-Values (*.csv) files) for the events where Windows Update fails to install the updates for my Office 2003 products.

I will now send the results (the *.csv files) to Microsoft, who will hopefully tell me how to fix this problem.

So much for the "Fully-Automatic, Trouble-Free Updates" that I keep hearing about.

I doubt that anyone with less than a couple of years training and experience in Microsoft products would have been able to do what I did, namely to know what I had to do, when the "official" description of what to do from the Microsoft website turns out to be incorrect.

Best regards,
